Baby sitting a baby cat which is 6 weeks old

Hello All,
I have one trouble and need your advice. My wife adopt a baby cat 2 weeks ago. She is 6 weeks old now. We will go for a 3 week holiday to our home country and one of my friend supposed to have her during that time. But the guy suddenly change his mind. Because she is 6 weeks old veterinary clinics are not accepting her. I am desperate and I do not know what to do ? Does anybody interested to keep her for 3 weeks. Or if anybody have a suggestion I will appreciate that.
